Is DDossing a thing in Catan Universe?browsing

So, I ended up in a Free match with two players who had really low karma. After placing our pieces game just freezed at third player, the player who had the lowest karma. So I strarted to wonder, If the game did not gave ma no disconnection warning, is there a way for other player to for example ddos other players or is it just a game bug?
Anyways, after 3 tries to re-connection and nothing changed, I exited the game and lost ELO. https://www.upload.ee/image/8168997/catandos.PNG
